Here are a list of the kinds of characters one can play in the
Systems Failure world:

Egghead - scientist type
Exterminator - Freedom Fighter/Bug Killer trained
Freebooter - Trader/supplier/smuggler
Grease Monkey - Mechanic
Peacekeeper - Town Marshal or a Badland Vigilante
Sawbones - Medic
Splatterpunk - Criminal lowlife of sorts
Survivalist - Militia
NORAD Psychic - Jedi types (sorry no lightsaber)
NORAD Splicer - Government experiment
Wacko - They may ride the small yellow bus, but they kick some ass.

All characters will also roll to see what their career was prior to
the bug invasion. However, the above character classes are what
defines the character's new line of work.

I'm flexable with any other ideas for a character, so bring up any
questions you may have.
